block: Make REQ_OP_ZONE_FINISH a write operation

Browse Source 
[ Upstream commit 3f66ccbaae ]

REQ_OP_ZONE_FINISH is defined as "12", which makes
op_is_write(REQ_OP_ZONE_FINISH) return false, despite the fact that a
zone finish operation is an operation that modifies a zone (transition
it to full) and so should be considered as a write operation (albeit
one that does not transfer any data to the device).

Fix this by redefining REQ_OP_ZONE_FINISH to be an odd number (13), and
redefine REQ_OP_ZONE_RESET and REQ_OP_ZONE_RESET_ALL using sequential
odd numbers from that new value.

Fixes: 6c1b1da58f ("block: add zone open, close and finish operations")
